To investigate whether the use of Corus CAD (Age/Sex/Gene Expression score - ASGES) blood assay changes the diagnostic testing pattern in patients referred to a cardiologist for the evaluation of chest pain or anginal equivalent symptoms.

Change in management practice pattern between preliminary and after Corus CAD (ASGES) decision [ Time Frame: Up to 7 days ]

Change in management pattern comparing the preliminary and after Corus CAD (ASGES) decision will be measured by the number of subjects with medical management downgrade or upgrade within the following predefined categories:

No further cardiac testing or treatment

Medical therapy for angina or non-cardiac chest pain

Stress testing with or without imaging

CT angiography

Invasive cardiac catheterization

Change in management practice pattern between after Corus CAD decision and historical cohort. [ Time Frame: up to 195 days ]

Change in management pattern comparing the Corus CAD (ASGES) driven decision and the historical cohort ill be measured by the number of subjects with medical management downgrade or upgrade within the following predefined categories:
